URSA Seco A is a vapor permeable, windproof membrane that allows the protection against moisture. URSA SECO A – protects thermal insulation and construction structures from damaging effects of moisture and wind. The membrane allows the vapour to pass through the thermal insulation. In facade systems, it is is directly connected to the thermal insulation from the outside. But in roof systems, at an angle greater than 35˚, its application is permitted and it must be installed with ventilation interval. Dimensions: 1,5*40m.
When this type of membrane is applied, the usage period of the thermal insulation layer extends to 50 years.
